移动的平铺显示器（MTD）是使用多个移动的终端来实现大型虚拟显示器的技术。由于MTD是由一组具有不同特性的终端组成的，终端之间的性能差异和网络环境的差异都会影响视频的播放。在这项研究中，我们提出了一种MTD配置方法，控制终端的窗口组成，考虑到终端的性能和网络特性。此外，我们开发了一种新的MTD系统，采用我们提出的方法。开发的系统旨在通过将具有良好通信质量的终端放置在屏幕的中心来减少终端特性差异的影响。作为开发的系统的评估，我们调查了初始窗口定位配置的时间开销。结果表明，在MTD中显示视频没有问题，尽管在16个终端的情况下需要大约4.5秒。此外，我们准备了几个MTD视频使用开发的系统，并进行问卷调查，从60人的观看体验的主观评价。说明我们开发的屏幕合成方法是有效的。
A Mobile Tiled Display (MTD) is a technology to realize a large virtual display using multiple mobile terminals. Since a MTD which composed of a group of terminals with different characteristics, differences in performance among terminals and differences in the network environment affect the video playback. In this study, we propose a MTD configuration method that controls the window composition of terminals in consideration of terminal performance and network characteristics. In addition, we develop a novel MTD system that incorporates our proposed method. The developed system aims to reduce the impact of differences in terminal characteristics by placing terminals with good communication quality in the center of the screen. As an evaluation of the developed system, we investigated the time over-head of the initial window positioning configuration. The result shows that there is no problem in displaying the video in MTD, although it takes about 4.5 seconds in the case of 16 terminals. Moreover, we prepare several MTD videos using the developed system, and conduct questionnaires for subjective evaluation of the viewing experience from 60 people. and we clarified the screen composition method we developed was effective.
